[0116] First and Second Aspects of this Disclosure

[0117] The basic structural principle and technical problem solved in this case is that by setting different height adjustment structures for the seat on the shoulder straps of the child carrier, and selectively connecting them with the body piece, the height adjustment of the seat and the disassembly and replacement of the body piece can be realized.

[0118] The present disclosure will now be described in detail with reference to the drawings, wherein Figures 1 to 8 show the structure of a child carrier 1 according to an embodiment of the first aspect of the present disclosure.

[0119] FIG1 schematically shows a front view of a child carrier 1 according to a first aspect of the present disclosure. The child carrier 1 includes a shoulder strap assembly 100 (also referred to as a "girder assembly") and a support piece 200 connected to the shoulder strap assembly 100. It should be noted that the term "support piece" here does not mean that the component is a "sheet-like piece," but may also be referred to as a "support member" or a "support assembly" composed of multiple components. The shoulder strap assembly 100 allows a user to wear the child carrier 1. Specifically, referring to FIG1, the dashed lines schematically show an adult wearing the child carrier 1 to carry a child.

[0120] The shoulder strap assembly 100 includes a shoulder strap 110 and a waist belt 120. In this embodiment, the shoulder strap 110 is composed of two shoulder straps 111, and the waist belt 120 is connected to the lower end (not shown in FIG1) of each shoulder strap 111 at the adult waist position and secured to the waist using, for example, snap fasteners. In one example, the two shoulder straps 111 of the shoulder strap 110 can be two separate components, but this disclosure is not limited thereto. The shoulder strap 110 can also be an integral structure, for example, the two shoulder straps 111 can be connected to each other to form the shoulder strap 110, and then the entire shoulder strap 110 (e.g., the lower end) is fixedly connected to the waist belt 320.

[0121] The support plate 200 includes a seat support area 210 (also referred to as a "seat support member") for a child to sit on, a body piece (also referred to as a "torso support member") 220 for holding the child's body, and a thigh support piece 230. It should be noted that "thigh support piece" does not necessarily mean a sheet-like component; it can also be referred to as a "thigh support member." One end of the seat support area 210 can be connected to the body piece 220 (e.g., one end there), and the other end can be connected to the waist belt 120. The thigh support pieces 230 are disposed on both sides of the seat support area 210 to provide support for the child's legs as they extend outward from the support plate 200. In one example, one end of the thigh support piece 230 is connected to the body piece 220, and the other end is connected to the waist belt 120.

[0122] For example, in the wearing configuration shown in FIG1, the support piece 200 is connected to the shoulder strap assembly 100 at the lower seat support area 210 and flipped upward, so that the upper end of the support piece 200 (i.e., the end of the body piece 220 away from the seat support area 210) can be fixedly connected to the upper end of the shoulder strap assembly 100 via a connector, such as a snap fastener, magnetic snap, or button, for example, to the shoulder straps 111 of the shoulder strap assembly 100. In this case, a receiving part for carrying a child can be formed between the shoulder strap assembly 100 and the support piece 200, and the child's legs can extend from both sides of the seat support area 210 via the thigh support piece 230 into the child carrier 1, making the child's riding more comfortable.

[0123] Figure 2 shows a front view of a child carrier 1 in a first carrying state according to an embodiment of the present disclosure. In order to enable the seat (i.e., the position that accommodates the child's buttocks) of the child carrier 1 of the present disclosure to be used at different heights, the child carrier 2 may be provided with a first seat height adjustment structure.

[0124] Specifically, to facilitate viewing the specific structure of the child carrier 1, Figure 2 shows that the connector used to connect the upper end of the shoulder strap assembly 100 and the upper end of the body piece 220 of the support piece 200 is opened. The body piece 220 is changed from the carrying position or child sitting position shown in Figure 1 to a hanging state, that is, hanging downwards. Thus, the inner side of the seat support area 210 and the thigh support pieces 230 on both sides of the seat support area 210, which were covered by the body piece 220 in Figure 1, can be seen. In this state, the shoulder strap assembly 100 is provided with a first connector 130. According to this embodiment, the first connector 130 is located on the connecting strap 112, which connects the two shoulder straps 111 laterally, for example, approximately parallel to the waist belt 120. In one example, the first connector 130 may be located in the middle part of the two shoulder straps 111, that is, at a distance from the lower end of the shoulder straps 111, but this disclosure is not limited to this. According to this disclosure, the connecting strap 112, while connecting the two shoulder straps 111, can also serve as a first connector, making the height adjustment structure of this disclosure more compact. Furthermore, the connecting strap 112 is a chest piece 112 suitable for contact with a child's chest, and the first connector 130 is located on the chest piece 112.

[0125] According to this embodiment, the first connector 130 can be in the form of a zipper or other connectors, such as snap fasteners or buttons. The first connector 130 is connected to the coupling 212 disposed on the upper side of the seat bearing area 210 of the support piece 200, thereby forming the first bearing state shown in FIG2. According to this embodiment, the coupling 212 is located on the edge of the seat bearing area 210 that engages with the first connector 130. Corresponding to the first connector 130, the coupling 212 can be in the form of a zipper or other connectors, such as snap fasteners or buttons.

[0126] According to this embodiment, the first connecting member 130 can be a female zipper tape with a zipper head, and the connecting member 212 can be a male zipper tape adapted to the female zipper tape; or the first connecting member 130 can be a male zipper tape, and the connecting member 212 can be a female zipper tape with a zipper head adapted to the male zipper tape. Here, the first connecting member 130 and the connecting member 212 are joined by the zipper head, so that the carrier piece 200 is fixedly connected to the shoulder strap 110.

[0127] According to this embodiment, a cover plate 131 may be provided on the outer side of the first connector 130 above the first connector 130. One side of the cover plate 131 is fixed to the connecting strip 112, and the opposite side is a movable side. By flipping the movable side, the first connector 130 can be covered or exposed. By providing the cover plate 131, the first connector 130 can be covered, thereby preventing children from being scratched or causing discomfort by things such as zippers, and also improving the aesthetics.

[0128] According to this embodiment, the movable edge of the shielding piece 131 is provided with a first fixing member 132, and the connecting strap 112 is provided with a second fixing member 133 corresponding to the first fixing member 132. For example, the first fixing member 132 is a hook and loop fastener, and the second fixing member 133 is a hook and loop fastener; or, the first fixing member 132 is a hook and loop fastener, and the second fixing member 133 is a hook and loop fastener; or, the first fixing member 132 is a female buckle, and the second fixing member 133 is a male buckle; or, the first fixing member 132 is a male buckle, and the second fixing member 133 is a female buckle; or, the first fixing member 132 is a first magnetic body, and the second fixing member 133 is a second magnetic body that is magnetically attracted to the first magnetic body.

[0129] FIG3 shows a front view of a child carrier 1 in a first carrying state according to an embodiment of the first aspect of the present disclosure. FIG3 shows the state in which the shielding plate 131 of FIG2 shields the first connector 130.

[0130] Figure 4 shows a front view of a child carrier 1 in a second carrying state according to an embodiment of the first aspect of this disclosure. As can be seen from the second carrying state shown in Figure 4, a second connector 140 can be provided below the first connector 130, at the lower end of the shoulder strap 111 of the shoulder strap 110. The second connector 140 is located at the junction of the waist belt 120 and the shoulder strap 110. According to this embodiment, the connector 212 is located on the edge of the seat carrying area 210 that engages with the second connector 140. However, this disclosure is not limited to this; the second connector 140 can also be provided above the lower end of the shoulder strap 111, as long as it is spaced a distance from the first connector 130. It is understood that in other examples, a third connector and / or a fourth connector can be provided between the first connector 130 and the second connector 140 to increase the adjustable height of the seat.

[0131] According to this embodiment, the second connector 140 can be a female zipper strap with a zipper head, and the connecting member 212 can be a male zipper strap adapted to the female zipper strap; or the second connector 140 can be a male zipper strap, and the connecting member 212 can be a female zipper strap with a zipper head adapted to the male zipper strap. Here, the second connector 140 and the connecting member 212 are connected by the zipper head, so that the seat bearing area 210 of the carrier piece 200 is fixedly connected to the lower edge of the waist belt 120. In this case, while the seat bearing area 210 for carrying the child is the same, the space for carrying the child is expanded, allowing the height and width of the carrier seat to be adjusted for larger infants and toddlers, to accommodate larger children or to provide infants and toddlers with more room to move.

[0132] As can also be seen in Figure 4, according to this embodiment, the seat support area 210 is symmetrically provided with side connecting ends 211 on both sides. The side connecting ends 211 on both sides can be connected to the thigh support pieces 230 on the corresponding sides, thereby forming a first opening 233 and a second opening 234 between the thigh support pieces 230 and the seat support area 210. For example, the side connecting ends 211 can be inserted into and connected to the thigh support pieces 230 on the corresponding sides. Specifically, the side connecting ends 211 are formed from a portion of the side of the seat support area 210. The first opening 233 and the second opening 234 allow the thigh support pieces 230, which contain hard sheets or other elastic padding, to undergo moderate deformation and displacement after a child sits in, thereby effectively improving the child's riding comfort.

[0133] FIG5 shows an exploded front view of a child carrier 1 according to a first aspect of the present disclosure. FIG5 shows a shoulder strap 110 and a waist belt 120 joined together as a shoulder strap assembly 100. The shoulder strap 111 extends from one side of the waist belt 120 and is fixed to a joint 121 where the waist belt 120 connects to the shoulder strap 110. This joint 121 can be fixed by any method, such as sewing, needle stitching, etc. Near the joint 121, for example on the waist belt 120, a second connector 140 is provided. A connecting strap 112 is provided at the upper edge of the waist belt 120, and a first connector 130 is provided on the connecting strap 112. If necessary, a cover plate 131, a first fastener 132, and a second fastener 133 can be provided (see description in FIG2).

[0134] According to this embodiment, the support piece 200 and the shoulder strap assembly 100 are separated, and a zipper-shaped connector 212 is provided at the upper edge of the seat support area 210. The zipper head can be provided on the connector 212 so as to engage with the first connector 130 and the second connector 140 respectively. It is understood that the seat height adjustment structure (i.e., the first seat height adjustment structure) of one embodiment of this disclosure may include the "first connector 130" and the "second connector 140", and / or other connectors provided between the first connector 130 and the second connector 140, so that the connector 212 can engage with connectors at different positions, thereby placing the seat of the child carrier 2 at different heights.

[0135] FIG6 shows a reverse view of a child carrier 1 according to an embodiment of the first aspect of the present disclosure. FIG6 shows the reverse side of FIG5, where the waist belt 120 covers and makes the rear-extending shoulder strap 111 invisible.

[0136] FIG7 shows a partial front view of the seat portion according to an embodiment of the first aspect of the present disclosure. FIG8 shows a partial reverse view of the seat portion according to an embodiment of the present disclosure, and FIG8 shows the reverse side of FIG7. In FIG7, a shoulder strap 111 is provided across the waist belt 120, and a connecting member 212 is engaged with a second connecting member 140 on the lower side of the waist belt 120. According to this embodiment, thigh support pieces 230 are provided on both sides of the seat support area 210, and each thigh support piece 230 is provided with a rigid sheet or other elastic filler. As shown in FIG7 and FIG8, the first connecting end 231 of the thigh support piece 230 is connected to the side edge 240 of the support piece 200 and forms a first opening 233 with the seat support area 210, and the second connecting end 232 is connected to the connecting member 212 and / or the side edge 240 of the support piece 200 and forms a second opening 234 with the seat support area 210. For example, both the first connecting end 231 and the second connecting end 232 are sewn onto the side 240 of the support piece 200 and the connecting member 212, respectively. According to this embodiment, the first connecting end 231 can be integral with the body piece 220 and sewn onto the thigh support piece 230, while the second connecting end 232 is sewn onto the connecting member 212. According to this embodiment, the second connecting end 232 at least covers a portion of the second opening 234.

[0137] According to this embodiment, the first opening 233 is larger than the second opening 234, but this disclosure is not limited thereto. By setting the first opening 233 to be larger than the second opening 234, the deformation of the seat bearing area 210 at the first opening 233 can be greater than that at the second opening 234, so that when the child sits facing the user of the child carrier 1, the child's legs can better form an M-shaped leg, thereby increasing the comfort of the child sitting in the child carrier 1.

[0138] According to this embodiment, the seat support area 210 is provided with a side connecting end 211, which is fixed to the middle section of the thigh support piece 230. The side connecting end 211 has a first arcuate portion 241 away from the connecting member 212, forming a first opening 233 with the thigh support piece 230. The side connecting end 211 has a second arcuate portion 242 near the connecting member 212, forming a second opening 234 with the thigh support piece 230. In one example, the thigh support piece 230 can be arranged along the first arcuate portion 241 and the second arcuate portion 242 to cover the first opening 233 and the second opening 234, thereby ensuring the support strength of the first opening 233 and the second opening 234 while ensuring external integrity and aesthetics. The curvature of the first arcuate portion 241 is greater than the curvature of the second arcuate portion 242, thereby making the structure of the seat support area 210 according to the first aspect of this disclosure more ergonomic and more comfortable for children to ride.

[0139] Figure 9 shows a front view of a child carrier 1 in a second carrying state according to another embodiment of the first aspect of this disclosure. According to this embodiment, the waist belt 120 covers and makes the rear-extending shoulder straps 111 invisible at that point, and the upper end of the seat bearing area 210 of the thigh support plate 230 that is engaged is also covered by the waist belt 120, which is connected to the two shoulder straps 111 or the waist belt 120.

[0140] According to this embodiment, a chest piece 112 is provided at the middle of the two shoulder straps 111 and spaced apart from the waist belt 120. The chest piece 112 is designed for the child's chest to rest against, and also serves as a connecting strap between the two shoulder straps 111 to make carrying more stable. In one example, a first connector 130 is provided at the lower end of the chest piece 112, for example, in the form of a female zipper strap with a zipper head or a female zipper end, while a connecting member 150 is provided at the upper end of the waist belt 120, for example, in the form of a male zipper strap corresponding to the female zipper strap. In this second carrying state, the connecting member 150 is separated from the first connector 130, so that the waist belt 120, together with the seat carrying area 210, is separated from the chest piece 112, thereby expanding the seating space above the seat carrying area 210 to accommodate larger children.

[0141] Figure 10 shows a front view of a child carrier 1 in a first carrying state according to another embodiment of the first aspect of this disclosure. According to this embodiment, the waist belt 120 together with the seat carrying area 210 is pulled close to the chest piece 112, such that the coupling 150 on the waist belt 120 engages with the first connecting member 130 on the chest piece 112, for example, the female zipper strap and the male zipper strap engage with each other, thereby reducing the seating space above the seat carrying area 210 to accommodate small children.

[0142] Figure 11 shows a partial front view of the child carrier 1 in the second carrying state of Figure 9. The first connector 130 on the chest piece 112, such as a female zipper strap with a zipper head, and the connector 150, such as a male zipper strap, at the waist belt 120 or at the sewn joint between the waist belt 120 and the shoulder strap 111, can be seen more clearly. Furthermore, as shown by the dotted lines in Figure 11, the male zipper strap can also be alternatively placed on the shoulder strap 111 or the waist belt 120 body, thus easily achieving adjustments for different heights. The male zipper strap can be placed not only on the upper side of the waist belt 120, but also between the upper and lower sides of the waist belt 120. The zipper head of the female zipper strap at the lower end of the chest piece 112 can easily engage with and pull the male zipper strap, so that the child carrier 1 is in the first carrying state shown in Figure 10. According to this disclosure, the male zipper strap can also be placed on the chest piece 112, while the female zipper strap can be placed on the waist belt 120, for example, on the upper side of the waist belt 120.

[0143] FIG12 shows a front view of a child carrier 1 in a second carrying state according to another embodiment of the first aspect of the present disclosure. FIG12 is a reverse front view of the child carrier 1 of FIG9, in which the shoulder straps 111 partially obscure the rear chest piece 112, so that only the portion of the first connector 130 located at the lower middle of the chest piece 112 can be identified. The connecting member 150 is separated from the first connector 130 and is partially obscured by the shoulder straps 111 in this embodiment. In this second carrying state, the seat carrying area 210 and the body piece 220 below it are in a lower position, thereby providing a larger seating space when the child is riding.

[0144] Figure 13 shows a front view of a child carrier 1 in a first carrying state according to another embodiment of the first aspect of this disclosure. According to this embodiment, the coupling 150 is engaged to the first connector 130, and the two shoulder straps 111 flexibly deform between the chest piece 112 and the waist belt 120, for example, protruding outwards as shown, thereby shortening the length of the shoulder straps 111. As a result, the position of the seat carrying area 210 and the body piece 220 below it is higher than the position shown in Figure 12, thus providing less seating space when a small child is riding in it.

[0145] FIG14 shows an exploded view of a child carrier 1 according to another embodiment of the first aspect of the present disclosure. FIG14 shows two shoulder straps 111 and a waist belt 120 that are joined together to form a shoulder strap assembly 100. The shoulder straps 111 extend from one side of the waist belt 120 and are fixedly joined at the connection between the waist belt 120 and the shoulder straps 111. The joining can be done by any fixing method, such as sewing, needle sewing, etc.

[0146] According to FIG14, a connecting member 150 is provided on the invisible rear side of the waist belt 120 (see the embodiment in FIG11), and a first connecting member 130 is provided on the chest piece 112. The first connecting member 130 and the connecting member 150 are in a separated state, so that the child carrier 1 is in a second carrying state.

[0147] According to FIG. 14, near the connection between the waist belt 120 and the shoulder strap 111, on the front side of the waist belt 120, the support piece 200 is detachably engaged with the shoulder strap 110 or the waist belt 120 via connecting devices 160 and 213. The connecting devices 160 and 213 are, for example, a male zipper tape 160 and a female zipper tape 213 with a zipper head adapted thereto, wherein the female zipper tape 213 is located on the edge of the seat support area 210 that engages with the shoulder strap assembly 100, and the male zipper tape 160 is located on the waist belt 120 or the shoulder strap 110, for example, at the connection between the waist belt 120 and the shoulder strap 110. The connecting devices 160 and 213 can also be, for example, buttons, snap fasteners, etc. The support piece 200 can also be fixedly engaged with the shoulder strap 110 or the waist belt 120, for example, by sewing.

[0148] Figures 15 and 16 show front views of a child carrier 1 in a second carrying state according to another embodiment of the first aspect of this disclosure.

[0149] In this embodiment, the chest piece 112 has a sandwich structure, for example, a sandwich composed of two or more layers of fabric, the sandwich being configured, for example, as a pocket shape with the opening facing downwards. An extension piece 170 is provided at the lower edge of the chest piece 112 that can be folded into the sandwich, and a first connector 130, for example, a female zipper tape with a zipper pull, is located on the extension piece 170. According to this embodiment, the extension piece 170 extends downwards from the lower edge of the outer fabric visible in FIG. 15, for example, the connecting portion 180. The extension piece 170 may also extend downwards from the lower edge of the inner fabric covered by the outer fabric in FIG. 15, or from the lower edges of both the inner and outer fabrics.

[0150] Additionally, the extension piece 170 may be provided with a third fastener 171. The third fastener 171 can be seen at the rear side of the extension piece 170 when it is lifted upwards in Figure 15. The extension piece 170 is secured by the third fastener 171 after being folded into the interlayer. The third fastener 171 may be a Velcro fastener, a snap fastener, or a magnetic fastener.

[0151] According to this embodiment, the third fastener 171 can cooperate with the corresponding fastener on the inner side of the outer fabric after being folded into the interlayer, so that the extension piece 170 together with the first connector 130 can be easily stored in the interlayer pocket of the chest piece 112. Referring to FIG16, the extension piece 170 together with the first connector 130, shown in dashed lines, is folded inward from near the connecting portion 180 and stored in the interlayer pocket of the chest piece 112, so that in the second carrying state, the unused first connector 130 does not affect the child's riding comfort and is properly stored. When the first carrying state is needed, the extension piece 170 together with the first connector 130 is first folded out from the interlayer, and then the first connector 130 is engaged to, for example, the engaging member 150 in FIG10.

[0152] According to this embodiment, the support piece 200 can be detached from the shoulder strap assembly 100, thereby allowing for convenient replacement of the support piece 200 or the shoulder strap assembly 100. The beneficial technical effect of this disclosure is that by providing seat height adjustment structures of different heights, such as zipper structures, on the shoulder strap 110, and selectively connecting them to the support piece 200 and / or to the shoulder strap 110 or waist belt 120 of the shoulder strap assembly 100, seat height adjustment can be achieved to accommodate infants and toddlers of different body sizes. Furthermore, the support piece 200 forms a detachable structure, facilitating the matching of support pieces 200 for different seasons and meeting diverse needs.

[0153] Furthermore, a second aspect of this disclosure also provides a child carrier 2. Referring to Figures 17 to 20, Figure 17 shows a front view of a child carrier 2 according to a first embodiment of the second aspect of this disclosure; Figures 18 and 19 show partial views of the child carrier 2 shown in Figure 17, wherein the first height adjustment member 510 and the second height adjustment member 520 are in different states; and Figure 20 shows a partial view of a child carrier 2 according to a second embodiment of the second aspect. It should be noted that the child carrier 2 of this disclosure has a use state in which a child is riding on it and a non-use state in which a child is not riding on it. Figure 17 shows the non-use state of the child carrier 2. Although the "use state" is not shown in the figure, the use state of the child carrier 2 should be understood from Figure 17.

[0154] Similar to the aforementioned embodiments, the child carrier 2 may include a shoulder strap assembly 300 and a support piece 400 connected to the shoulder strap assembly 300. As shown in Figures 17 and 18, the shoulder strap assembly 300 allows the user to wear the child carrier 2. Specifically, the shoulder strap assembly 300 may include a shoulder strap 310 and a waist belt 320. The waist belt 320 can be fastened around the user's waist. For example, the two ends of the waist belt 320 can be connected to each other by means of snap-fit, fastening, Velcro, etc., to wrap around and fix it around the user's waist. One end of the shoulder strap 310 is connected to the waist belt 320, for example, by sewing, but this disclosure is not limited to this. The shoulder strap 310 may also be connected to the waist belt 320 by a detachable connection.

[0155] In one example, the shoulder strap 310 may include two shoulder straps 311, one end of each shoulder strap 311 (as lower end) being fixedly connected to the waist belt 320. However, this disclosure is not limited thereto, and the shoulder strap 310 may also be an integral structure, for example, the two shoulder straps 311 are connected to each other, and the lower end of the entire shoulder strap 310 is fixedly connected to the waist belt 320.

[0156] Referring to Figures 17 and 18, the support piece 400 may include a seat support area 410, a body piece 420, and a thigh support piece 430. The seat support area 410 extends along the lateral direction D2 of the child carrier 2 to form a seat area for the child to sit on and to support the child's buttocks. One end of the seat support area 410 is connected to the body piece 420, and the other end of the seat support area 410 is connected to the waist belt 320, for example, by means of sewing. The body piece 420 may also be referred to as a "torso support" and is configured to hold the child's body. When the child carrier 2 is in the use state shown in Figure 17 (i.e., worn), the other end of the body piece 420 can be detachably connected to the upper end of the shoulder strap assembly 300 (e.g., shoulder strap 310) by means of snaps, fasteners, buttons, etc., so that at least a portion of the support piece 400 is flipped upward (see Figure 17) to form a receiving part for carrying the child.

[0157] In one example, the seat support area 410 and / or the body piece 420 may be made of a fabric with properties such as waterproofness and breathability, but this disclosure is not limited thereto. In other examples, the seat support area 410 and / or the body piece 420 may also be made of mesh fabric (i.e., a material with a mesh texture) to increase breathability and stretchability, and to reduce weight. Optionally, the seat support area 410 and the body piece 420 may be made of the same material or different materials. Furthermore, the seat support area 410 may be fixedly connected to the body piece 420, for example, by sewing. Optionally or alternatively, the seat support area 410 may be integrally molded with the body piece 420, for example, integrally molded from the same material.

[0158] In this embodiment, the thigh support plate 430 can be disposed on both sides of the seat support area 410. Specifically, one end of the thigh support plate 430 (e.g., the first connecting end 431) is connected to the body piece 420, and the other end of the thigh support plate 430 (e.g., the second connecting end 432) is connected to the waist belt 320. An opening is formed between the thigh support plate 430 and the seat support area 410 to provide deformation space for the seat support area 410 when the child sits. Other specific structures of the support plate 400 can be found in the various embodiments of the first aspect described above, and will not be repeated here.

[0159] In this embodiment, as shown in Figures 18 and 19, the child carrier 2 may also be provided with a second seat height adjustment structure. The second seat height adjustment structure may include a first height adjustment member 510 and a second height adjustment member 520. In one example, the first height adjustment member 510 is disposed on the seat support area 410, and the second height adjustment member 520 is disposed on the waist belt 320, and can engage and disengage with the corresponding first height adjustment member 510, such that when the first height adjustment member 510 and the second height adjustment member 520 are engaged with each other, the dimension of the area of ​​the seat support area 410 that carries the child (i.e., the seat area) along the longitudinal direction D1 and / or the length of the body piece 420 along the longitudinal direction D1 is shortened. In other words, when the child carrier 2 is in the use state shown in Figure 17, and the first height adjustment member 510 and the second height adjustment member 520 are engaged, the height of the seat support area 410 (i.e., the seat area) is raised, thereby adjusting the height of the seat of the child carrier 2.

[0160] In another example, the first height adjustment member 510 may also be disposed at the connection between the body 420 and the seat bearing area 410, or on the body 420 and close to the connection. Optionally or alternatively, the second height adjustment member 520 may also be disposed on the seat bearing area 410 and located at a different position from the first height adjustment member 510 in the longitudinal direction D1, but this disclosure is not limited thereto.

[0161] Specifically, as shown in Figures 18 and 19, the first height adjustment member 510 can be a connecting buckle, such as a button. In one example, as shown in Figures 20 and 21, the first height adjustment member 510 is connected to the seat bearing area 410 or the body piece 420 in the longitudinal direction D1 via two connection points. These two connection points are approximately aligned in the longitudinal direction D1, making it easier for the first height adjustment member 510 to be concealed by the wing portion in the lateral direction D2, thus improving the product's aesthetics. The second height adjustment member 520 can be correspondingly designed as a loop, such as a fabric loop. However, this disclosure is not limited to this; the first height adjustment member 510 and the second height adjustment member 520 can also be designed as hook and loop assemblies, buckle assemblies, straps, etc., that can engage with each other.

[0162] In this embodiment, taking the first height adjustment member 510 as a button and the second height adjustment member 520 as a fabric loop as an example, the fabric loop can be fixedly set at or near the upper end of the waist belt 320. For example, one end of it can be fixed to the waist belt 320 by sewing (as shown in the first fixing point P1 in FIG18). Optionally, as shown in FIG18 and FIG19, the sewing line used to fix the fabric loop (i.e., the sewing line corresponding to the first fixing point P1) can be spaced apart from the upper edge of the waist belt 320 and / or the junction of the seat bearing area 410 and the waist belt 320 (such as the sewing line of the two), that is, they do not overlap, but this disclosure is not limited to this.

[0163] In the second embodiment of this aspect, the second height adjustment member 520 can be connected to the waist belt 320 through at least two fixing points. Specifically, as shown in FIG20, the second height adjustment member 520 (taking a "cloth loop" as an example) can be fixed to the waist belt 320 through a first fixing point P1 and a second fixing point P2. The first fixing point P1 is similar to that shown in the previous embodiment, and the second fixing point P2 can be set in the middle of the cloth loop (for example, corresponding to another stitch line spaced apart from the first fixing point P1), so that the second height adjustment member 520 can be more stably and firmly fixed to the waist belt 320.

[0164] By providing a second seat height adjustment structure, that is, by cooperating with the first height adjustment member 510 and the second height adjustment member 520, the seat height of the child carrier 2 can be further adjusted, especially when the child carrier 2 is being worn. Specifically, the second height adjustment member 520 is provided on the waist belt 320, for example, near the upper end of the waist belt 320, which makes the overall structure of the second seat height adjustment structure more stable, thereby providing more secure support, and also has a more obvious identification (it is easier for the user to understand that the second height adjustment member 520 is a structure for height adjustment), thereby preventing misuse.

[0165] Furthermore, when the child carrier 2 is used and the child is riding in the child carrier 2 (i.e., when the child carrier 2 is in use), regardless of whether the first height adjustment member 510 and the second height adjustment member 520 are engaged, the second height adjustment member 520 is always blocked by the child's buttocks (i.e., the seat support area 410) when viewed from the user's front-back direction, making the child carrier 2 more aesthetically pleasing. In addition, the position of the first height adjustment member 510 in the longitudinal direction D1 can also be set such that, regardless of whether the first height adjustment member 510 and the second height adjustment member 520 are engaged, the first height adjustment member 510 is always blocked by the child's buttocks when viewed from the user's front-back direction.

[0166] In one example, the thigh support plate 430 may include a flap portion 4302. Referring to Figures 17 to 19, the flap portion 4302 may be configured to have at least a portion extending inward from the connection between the seat support area 410 and the thigh support plate 430, thereby at least partially concealing, in the lateral direction D2, the first height adjustment member 510, whether engaged with or not with the second height adjustment member 520, to maintain aesthetics. Optionally, the thigh support plate 430 is connected to the waist belt 320 and the body piece 420 respectively in the longitudinal direction D1 of the child carrier 2 via the flap portion 4302, that is, one end of the flap portion 4302 in the longitudinal direction D1 (i.e., the first connecting end 431) is connected to the body piece 420, and the other end of the flap portion 4302 in the longitudinal direction D1 (i.e., the second connecting end 432) is connected to the waist belt 320.

[0167] Further, as shown in FIG18, the thigh support plate 430 may also include a thigh support body portion 4301, which may extend laterally (i.e., in direction D2) outward from the wing portion 4302 to support the legs of the child sitting in the child carrier 2.

[0168] It should be noted that, although not specifically described, it should be understood that the various embodiments of the second aspect of this disclosure can also be used in combination with or alternative to the structures of the various embodiments of the first aspect described above, such as the first seat height adjustment structure composed of the first connector 130 and the second connector 140, etc., which will not be elaborated here.

[0169] The structure of the carrier sheet 400 will be described in detail below with reference to specific embodiments. Referring to Figures 21 and 22, the specific structures of the carrier sheet 400 according to two embodiments of the second aspect of this disclosure are shown respectively.

[0170] As shown in FIG21, similar to the previous embodiment, the support piece 400 of this embodiment may include a seat support area 410, a body piece 420, and a thigh support piece 430. The seat support area 410 forms a seat area for a child to sit on, with one end connected to the body piece 420 and the other end connected to the waist belt 320. The thigh support pieces 430 are disposed on both sides of the seat support area 410. One end (i.e., the first connecting end) of the thigh support piece 430 is connected to the body piece 420 and / or the seat support area 410 (e.g., its side), while the other end (i.e., the second connecting end) is connected to the waist belt 320. Specifically, a portion of the thigh support piece 430 is connected to the seat support area 410 and / or the body piece 420, and forms a first opening 433 and a second opening 434 with the seat support area 410 to provide deformation space for the seat support area 410 when the child is sitting in the child carrier 2.

[0171] Specifically, in this embodiment, the seat support area 410 may include a hip support body 411 extending along the lateral direction D2 of the child carrier 2. The hip support body 411 extends from the waist belt 320 to the body piece 420 along the longitudinal direction D1, that is, one end of the hip support body 411 is connected to the waist belt 320, and the other end is connected to the body piece 420. Optionally, the hip support body 411 is generally located at the center of the seat support area 410 along the lateral direction D2. In one example, as shown in FIG21, the lateral width of the end of the hip support body 411 near the waist belt 320 is smaller than the lateral width of the end near the body piece 420, that is, the end of the hip support body 411 near the waist belt 320 may be narrower, while the end near the body piece 430 may be wider. When a child sits facing the user in the child carrier's accommodating section, the child's legs need to spread wider, forming a distinct M-shaped leg. This design makes the portion of the buttocks support body 411 for the child's buttocks to sit on (i.e., the sitting portion) wider, with a larger deformation allowance. Older children (such as children over 6 months old) usually sit facing away from the user in the child carrier, and their legs tend to extend more naturally. Therefore, the sitting portion of the buttocks support body 411 is narrower, so that the child's buttocks do not sink down too much when sitting facing away.

[0172] Further, the seat support area 410 may also include a hip support connection portion 412. The hip support body portion 411 and the hip support connection portion 412 are connected to each other, for example, by stitch L13 and / or stitch L14 as shown in FIG. 21. One end of the hip support connection portion 412 is connected to the waist belt 320, and the other end extends along at least a portion of the hip support body portion 411 in the longitudinal direction D1, and optionally, extends to the longitudinal middle of the hip support body portion 411. At least a portion of the thigh support piece 430 located between the two connecting ends is connected to the seat support area 410 via the hip support connection portion 412.

[0173] In one example, the hip support connector 412 may be configured as a reinforcement (also referred to as a "first reinforcement") provided on the hip support body 411 to increase the material strength on both sides of the seat bearing area 410 and / or strengthen the connection strength between the seat bearing area 410 and the thigh support plate 430. The strength of the hip support connector 412 may be greater than the strength of the hip support body 411. Optionally, the thickness of the hip support connector 412 may be greater than the thickness of the hip support body 411. Optionally or alternatively, the material strength of the hip support connector 412 may be greater than the material strength of the hip support body 411.

[0174] Furthermore, the elasticity of the hip support body 411 can be greater than that of the hip support connecting part 412. That is, the area of ​​the seat bearing area 410 without reinforcement (i.e., the hip support connecting part 412) can have better extensibility, so that the seat bearing area 410 near the body piece 420 has a larger expandable width, which is beneficial for children to better form an M-leg effect when sitting facing the user. In an optional example, the hip support body 411 and the hip support connecting part 412 can have the same material but different thicknesses. However, this disclosure is not limited to this, and the hip support body 411 and the hip support connecting part 412 can also be made of different materials.

[0175] In a specific example, as shown in FIG21, a first height adjustment member 510 is provided on the outer region of the seat bearing area 410 corresponding to the hip support connection portion 412 (where "outer region" refers to the side of the child carrier 2 away from its receiving portion when worn), and a second height adjustment member is correspondingly provided on the waist belt 320 (not shown in FIG21, see FIG18 and FIG19 in conjunction). Similar to the previous embodiment, the first height adjustment member 510 and the second height adjustment member 520 can engage with each other to shorten the length of the seat bearing area 410 and / or the body piece 420 in the longitudinal direction D1, thereby adjusting the height of the carrier seat.

[0176] Specifically, as shown in FIG21, at least a portion of the thigh support plate 430 located between the two connecting ends (i.e., the first connecting end and the second connecting end) is connected to the seat support area 410 via the hip support connecting portion 412. In one example, the thigh support plate 430 includes a thigh support body portion 4301 and a flap portion 4302. The thigh support body portion 4301 is configured to support the child's legs. The flap portion 4302 may be configured to have at least a portion extending inward in the lateral direction D2 from the connection between the seat support area 410 and the thigh support plate 430. One end of the flap portion 4302 in the longitudinal direction D1 is connected to the body piece 420, and the other end in the longitudinal direction D1 is connected to the waist belt 320. Optionally, the thigh support body portion 4301 is located outside the flap portion 4302 in the lateral direction D2 and extends outward.

[0177] Furthermore, as shown in FIG21, the thigh support piece 430 may be provided with a first stitch line L11, which defines the thigh support piece 430 as a thigh support body part 4301 and a wing part 4302. Optionally, in the longitudinal direction D1, the first stitch line L11 is a curve that bends laterally inward in the middle. Optionally, the stitch line L13 (which may be referred to here as the third stitch line, or may also serve as the binding line of the hip support connecting part 412) used to connect the hip support body part 411 and the hip support connecting part 412 may at least partially coincide with the first stitch line L11.

[0178] Furthermore, the thigh support piece 430 may also be provided with a second seam L12, which extends at least partially parallel to the first seam L11 and is located laterally inside or laterally outside the first seam L11. As shown in FIG21, the first seam L11 and the second seam L12 define a buffer connection area 4303, which is located between the flap portion 4302 and the thigh support body portion 4301 in the lateral direction D2. Optionally, the seat bearing area 410 (specifically its buttock support connection portion 412) can be connected to the thigh support piece 430 via a portion of the second seam L12.

[0179] By setting two parallel stitches, namely the first stitch L11 and the second stitch L12, the manufacturing stability of the child carrier can be improved, and the strength of the thigh support plate 430 itself can be increased, especially the connection strength between the thigh support body 4301 and the wing plate 4302. Furthermore, the buffer connection area 4303 can form a connection buffer between the wing plate 4302 and the thigh support body 4301, which have different thicknesses, so that the thigh support body 4301 can better provide upward support when subjected to downward pressure, making the thigh support plate 430 provide more stable support for the child's legs.

[0180] In one example, the thickness of the thigh support body portion 4301 may be greater than the thickness of the buffer connection area, and the thickness of the buffer connection area may be greater than the thickness of the wing portion 4302. Additionally or optionally, the thickness of the wing portion 4302 may be greater than the thickness of the seat bearing area 410.

[0181] Referring to FIG22, a partial view of a child carrier according to yet another embodiment is shown.

[0182] Similar to the previous embodiments, the support piece 400 in this embodiment may include a seat support area 410, a body piece 420, and a thigh support piece 430. The seat support area 410 may include a hip support body part 411 and a hip support connecting part 412. The hip support body part 411 and the hip support connecting part 412 may be separated by a stitch L26, for example, similar to L14 in the previous embodiments. The thigh support piece 430 is disposed on both sides of the seat support area 410 and connected between the waist belt 320 and the body piece 420. A first stitch L21 (similar to L11 in the previous embodiments) is provided on the thigh support piece 430, dividing it into a thigh support body part 4301 and a wing part 4302.

[0183] Optionally, as shown in FIG22, a second stitch L22 is also provided on the thigh support piece 430. The buttock support connecting portion 412 of the seat bearing area 410 is connected to the thigh support piece 430, for example, via the second stitch L22, specifically connected to the thigh support body portion 4301 and / or the wing portion 4302. In this embodiment, the first stitch L21 and the second stitch L22 coincide. However, this disclosure is not limited to this; the first stitch L21 may not coincide with the second stitch L22, for example, the second stitch L22 may be located inside the first stitch L21. In this embodiment, the two ends of the second stitch L22 in the longitudinal direction do not extend to the edge of the buttock support connecting portion 412. In other embodiments, the two ends of the second stitch L22 in the longitudinal direction may extend to the edge of the buttock support connecting portion 412.

[0184] As shown in FIG22, the third stitch L23 provided on the seat bearing area 410 can be configured as the binding line of the buttock support connection 412, and optionally, the third stitch L23 can also strengthen the connection between the buttock support connection 412 and the thigh support piece 430.

[0185] In this embodiment, the longitudinal middle part of the buttock support connecting part 412 can protrude laterally outward so that the seat bearing area 410 can better form a pocket shape, and a three-dimensional pocket can be cut out so that the child's thighs can more easily form an M-leg configuration when sitting. However, this disclosure is not limited to this, and the buttock support body part 411 may not form a pocket shape, but the elasticity of the buttock support body part 411 needs to be sufficient.

[0186] In one example, the end of the hip support body 411 near the waistband 320 can be narrower, while the end near the body piece 430 can be wider. This is because when a child sits facing the user in the child carrier's receiving part, the child's legs need to spread wider, forming a distinct M-shaped leg. This design allows for a wider portion of the hip support body 411 for the child's hips to sit on (i.e., the sitting portion), providing greater deformation allowance. Older children (e.g., children over 6 months old) usually sit facing away from the user in the child carrier, and their legs tend to extend more naturally. Therefore, the sitting portion of the hip support body 411 is narrower, so that the child's hips do not sink down too much when sitting facing away.

[0187] Optionally, a fourth stitch L24 may also be provided on the hip support connecting part 412 to further fix the hip support connecting part 412 to the hip support body part 411, thereby preventing the hip support connecting part 412 from shrinking too much when not in use, and / or to assist in connecting the hip support connecting part 412 and the wing part 4302, so that the connection between the seat bearing area 410 and the thigh support piece 430 is more stable.

[0188] Optionally or alternatively, a second reinforcement 4111 may be provided on the front side of the hip support body 411 (the side opposite to that shown in FIG. 22). The second reinforcement may be provided on the hip support body 411 near the waist belt 320, for example by being fixedly connected by the fifth stitch L15 (see FIG. 21) and L25 (see FIG. 22) to increase the overall durability of the child carrier 2.

[0189] In this embodiment, the thickness of the thigh support piece 430 is greater than that of the seat bearing area 410. Optionally, the thickness of the thigh support body 4301 is greater than that of the wing piece 4302, for example, by filling the thigh support body 4301 with more foam. Optionally, the thickness of the wing piece 4302 is greater than that of the hip support connecting portion 412. Optionally or alternatively, the thickness of the hip support connecting portion 412 may be greater than that of the hip support body 411. By gradually varying the thickness of each area, children can better form M-shaped legs when sitting.

[0190] Furthermore, the strength of the hip support connecting portion 412 is greater than the strength of the hip support body portion 411, and / or the elasticity of the hip support body portion 411 is greater than the elasticity of the hip support connecting portion 412, but this disclosure is not limited thereto.

[0191] Third aspect of this disclosure

[0192] A third aspect of this disclosure provides an infant carrier. As shown in Figures 23 to 25, the infant carrier includes a waist belt A1, shoulder straps A2, and a child support member A3 connected to both the waist belt A1 and the shoulder straps A2. The shoulder straps A2 are arranged generally along the longitudinal direction of the child support member A3. One side of the child support member A3 is connected to the waist belt A1, and the side of the child support member A3 away from the waist belt A1 is detachably or non-detachably connected to the shoulder straps A2. That is, the upper side of the child support member A3 is connected to the shoulder straps A2, and the lower side of the child support member A3 is connected to the waist belt A1. In this embodiment, the upper side of the child support member A3 is detachably connected to the shoulder straps A2 via a connecting component (e.g., a buckle). In other embodiments, the child support member A3 may be fixedly connected to the shoulder straps A2. This application does not limit the specific connection method between the child support member A3 and the shoulder straps A2. Referring to Figures 23 to 25, the child support A3 includes a hip support portion A31 and a torso support portion A32 connected to each other. In this embodiment, the child support A3 is integrally formed. The side of the hip support portion A31 away from the torso support portion A32 is connected to the waist belt A1, and the side of the torso support portion A32 away from the hip support portion A31 is connected to the shoulder strap A2.

[0193] It is worth noting that the depth direction of the child support A3 mentioned in this article specifically refers to the direction from the side where the child support A3 is connected to the waist belt A1 to the side where the child support A3 is connected to the shoulder strap A2, that is, the direction from the lower side to the upper side or from the upper side to the lower side of the child support A3.

[0194] Further, as shown in Figures 23 to 25, the infant carrier also includes a connector A4 connecting the waist belt A1 and the shoulder strap A2. A receiving space for accommodating the infant is formed between the connector A4 and the child support A3. The connector A4 includes a first connector A41 and a second connector A42. The first connector A41 is a generally rectangular piece of fabric. There are two first connectors A41, spaced apart and connected to the corresponding shoulder strap A2. The two ends of the second connector A42 are respectively connected to the two first connectors A41. In one embodiment, the connector A4 may also be a one-piece fabric piece, with one side connected to the waist belt A1 and the other side connected to the shoulder strap A2. In yet another embodiment, the infant carrier may not include the connector A4; instead, the shoulder strap A2 extends directly to the waist belt A1 and connects to it.

[0195] Referring to Figures 23 to 25, the side of the torso support A32 away from the hip support A31, i.e., the side of the child support A3 away from the waist belt A1, is detachably connected to the shoulder strap A2, thus facilitating the infant's entry and exit from the carrying space. In use, the waist belt A1 can be first fixed to the caregiver's waist, and the shoulder strap A2 can be suspended from the caregiver's shoulders. At this time, the connector A4 is against the caregiver's torso, and then the infant can be picked up. The side of the child support A3 away from the waist belt A1 is then connected to the shoulder strap A2, allowing the infant to sit within the carrying space. In this embodiment of the infant carrier, the carrying space is formed by the connector A4 and the child support A3, providing good wrapping and protection for the infant.

[0196] Further, as shown in Figures 25, 26, 28, and 29, the infant carrier also includes leg supports A51. In this embodiment, there are two leg supports A51, which are respectively disposed on both sides of the hip support A31 in the horizontal width direction, that is, on the left and right sides of the hip support A31. The hip support A31 and the leg supports A51 form a seat area A101 for supporting the infant. One end of the leg support A51 is connected to one end of the hip support A31 and is connected to the waist belt A1 to form a first fixed end A511 of the leg support A51 and the hip support A31, and the other end of the leg support A51 is connected to the other end of the hip support A31 to form a second fixed end A512 of the leg support A51 and the hip support A31. The natural depth L1 of the leg support A51 between the first fixed end A511 and the second fixed end A512 is smaller than the natural depth L2 of the hip support A31 between the first fixed end A511 and the second fixed end A512, so that the hip support A31 can be switched between an extended state and a retracted state in the depth direction of the child support A3. When the hip support A31 is in the extended state in the depth direction, the seat area A101 has a larger dimension in the depth direction; when the hip support A31 is in the retracted state in the depth direction, the seat area A101 has a smaller dimension in the depth direction. In actual use, when an infant or toddler sits on the seat area A101, the hip support A31 will be in the extended state due to the infant's own weight; when the infant or toddler is not sitting on the seat area A101, the hip support A31 will be in the naturally retracted state.

[0197] It is worth noting that the horizontal width direction of the child support A3 mentioned in this article specifically refers to the direction from the left side to the right side or from the right side to the left side of the child support A3, while the vertical depth direction of the child support A3 mentioned in this article specifically refers to the direction from the side where the child support A3 is connected to the waist belt A1 to the side where the child support A3 is connected to the shoulder strap A2, that is, the direction from the lower side to the upper side or from the upper side to the lower side of the child support A3. The natural depth dimension of the leg support A51 mentioned in this article between the first fixed end A511 and the second fixed end A512 refers to the actual length of the fabric forming the leg support A51 between the first fixed end A511 and the second fixed end A512 in the non-connected state. The natural depth dimension of the hip support A31 mentioned in this article between the first fixed end A511 and the second fixed end A512 refers to the actual length of the fabric forming the hip support A31 between the first fixed end A511 and the second fixed end A512 in the non-connected state.

[0198] In this embodiment, as shown in Figures 25 to 27, the hip support portion A31 is formed of a sheet of fabric. The hip support portion A31 is generally axially symmetrical, with its axis of symmetry being the longitudinal centerline extending along the depth direction of the child support member A3. The hip support portion A31 has first edges A311 on both sides of the child support member A3 in the lateral width direction, that is, both the left and right sides of the hip support portion A31 have first edges A311. Taking one of the first edges A311 as an example, the first edge A311 includes an arc-shaped segment A3111 and a recessed segment A3112 connected to each other. The arc-shaped segment A3111 extends gradually away from the longitudinal centerline of the hip support portion A31 from the first fixed end A511 towards the second fixed end A512. The recessed segment A3112 is connected to the arc-shaped segment A3111 and is recessed towards the longitudinal centerline of the hip support portion A31. During the manufacturing process, the buttock support A31 can be made by first cutting out the shape of the recessed sections A3112 on both sides from a roughly rectangular sheet of fabric, then folding it to form the shape of the arc-shaped sections A3111 on both sides, and finally sewing it together to form the shape with the aforementioned first edge A311. In this embodiment, the arc-shaped section A3111 extends outward to facilitate the formation of the widest support dimension away from the first fixed end A511, which is beneficial for the buttocks to have the widest support area when the baby is sitting. At the same time, the arc-shaped section A3111 forms the smallest support dimension near the first fixed end A511, which facilitates the support of the leg support A51 and the fixed sewing connection with the waist belt A1. The recessed section A3112 is close to the second fixed end A512. Since the leg support A51 and the hip support A31 have different longitudinal lengths, the recessed section A3112 facilitates the fixed connection between the leg support A51 and the hip support A31 at the recessed section A3112 through the second fixed end A512. It also facilitates the setting of the second opening A103 at the recessed section A3112, which not only ensures the ease of manufacturing but also makes the overall appearance more aesthetically pleasing.

[0199] Furthermore, the hip support A31 is provided with a first connecting portion A312 on both sides of the child support A3 in the lateral direction near the first edge A311. The first connecting portion A312 is a linear connecting portion located between the first fixed end A511 and the second fixed end A512.

[0200] In this embodiment, both leg supports A51 are generally long strip-shaped fabric structures, and the shapes and structures of the two leg supports A51 are basically the same. Taking one of the leg supports A51 as an example, as shown in Figures 25 and 26, the leg support A51 has a first support portion A513 and a second support portion A514. The thickness of the first support portion A513 is greater than the thickness of the second support portion A514, and the thickness of the first support portion A513 is greater than the thickness of the child support A3. In this embodiment, the thickness of the first support portion A513 can be greater than the thickness of the second support portion A514, and the thickness of the second support portion A514 can be greater than the thickness of the child support A3. In this way, the thigh support can provide stronger support for the thighs of infants and young children. In this embodiment, the first support portion A513 can be a multi-layer structure, for example, filled with a rigid filler such as cardboard or an elastic filler such as cotton between two layers of fabric, so that the first support portion A513 has a large thickness. As shown in Figure 28, the second support part A514 covers the back of the hip support part A31 to form an auxiliary support wing part when the infant carrier is used.

[0201] Specifically, as shown in Figures 26 and 28, the leg support A51 includes an outer edge A515 away from the hip support A31 and an inner edge A516 close to the hip support A31, both of which are straight edges. In this embodiment, since one end of the leg support A51 is connected to the waist belt A1, the outer edge A515 of the leg support A51 can be designed as a straight edge, which is more aesthetically pleasing and easier to process. The leg support A51 also has a dividing edge A517 located between the outer edge A515 and the inner edge A516. The portion of the leg support A51 located between the outer edge A515 and the dividing edge A517 forms a first support portion A513, and the portion of the leg support A51 located between the inner edge A516 and the dividing edge A517 forms a second support portion A514. In this embodiment, the leg support A51 is a long strip of fabric structure made of double-layered fabric, with an arc-shaped dividing edge A517 roughly along the depth direction of the child support A3 in its approximately central part. The dividing edge A517 can be a stitched line, thereby dividing the leg support A51 into a first support part A513 and a second support part A514. The part near the outer edge A515 is the first support part A513, which is filled with the hard or soft filler as described above and has a larger thickness, while the part near the outer edge A515 is the second support part A514, which has no filler and is only a double-layered fabric structure, so it has a smaller thickness. As shown in Figures 25 and 26, due to the arc shape of the dividing edge A517, the first fixing end A511 is formed from one side of the first support part A513 and one side of the second support part A514, while the second fixing end A512 is formed only from one side of the second support part A514.

[0202] Further, as shown in Figures 26 and 28, the leg support member A51 is also provided with a second connecting part A518 that can be connected to the first connecting part A312. It can be understood that the second connecting part A518 is also a linear connecting part located between the first fixed end A511 and the second fixed end A512. In this embodiment, the first connecting part A312 and the second connecting part A518 are sewn together. Of course, in other embodiments, the first connecting part A312 and the second connecting part A518 can also be connected by means of bonding or other methods. In this embodiment, the second connecting part A518 is approximately located in the middle of the leg support member A51 and is approximately set along the dividing edge A517, that is, the second connecting part A518 is offset from the outer edge A515 and also offset from the inner edge A516.

[0203] Furthermore, the first connecting part A312 and the second connecting part A518 can be configured in various ways so that the leg support A51 and the hip support A31 have different matching conditions.

[0204] For example, in the first embodiment, as shown in Figures 28 to 30, the first connecting part A312 and the second connecting part A518 are both connected to the second fixed end A512 and spaced apart from the first fixed end A511. The portion of the leg support A51 located between the first fixed end A511 and the second connecting part A518 and the portion of the child support A3 located between the first fixed end A511 and the first connecting part A312 form a first opening A102, that is, the first opening A102 is formed between the portion of the leg support A51 near the waist belt A1 and the portion of the hip support A31 near the waist belt A1.

[0205] In the second embodiment, as shown in Figures 31 and 32, the first connecting portion A312 and the second connecting portion A518 are located between the first fixed end A511 and the second fixed end A512 and are spaced apart from both the first fixed end A511 and the second fixed end A512. The portion of the leg support A51 located between the first fixed end A511 and the second connecting portion A518 and the portion of the hip support A31 located between the first fixed end A511 and the first connecting portion A312 form a first opening A102. At the same time, the portion of the leg support A51 located between the second fixed end A512 and the second connecting portion A518 and the portion of the hip support A31 located between the second fixed end A512 and the first connecting portion A312 form a second opening A103. A first opening A102 is formed between the portion of the leg support A51 near the waist belt A1 and the portion of the hip support A31 near the waist belt A1, while a second opening A103 is formed between the portion of the leg support A51 away from the waist belt A1 and the corresponding portion of the hip support A31 away from the waist belt A1.

[0206] In the third embodiment, as shown in FIG33, the first connecting part A312 and the second connecting part A518 are both connected to the first fixed end A511 and spaced apart from the second fixed end A512. The portion of the leg support A51 located between the second fixed end A512 and the second connecting part A518 and the portion of the hip support A31 located between the second fixed end A512 and the first connecting part A312 form a second opening A103, that is, the portion of the leg support A51 away from the waist belt A1 and the corresponding portion of the hip support A31 away from the waist belt A1 form a second opening A103.

[0207] In the fourth embodiment, as shown in FIG34, the first connecting part A312 and the second connecting part A518 both extend continuously from the first fixed end A511 to the second fixed end A512, that is, the leg support A51 and the hip support A31 are completely sewn together, and no opening is formed between the leg support A51 and the hip support A31.

[0208] In the above embodiment, if a first opening A102 or a second opening A103 is formed between the leg support A51 and the hip support A31, it is beneficial to the flexible connection and movement adjustment between the leg support A51 and the first connecting part A312.

[0209] Further, as shown in Figure 27, the hip support portion A31 has a first edge A311 on both sides in the horizontal direction. The distance W1 between the first fixed ends A511 of the two leg supports A51 located on both sides of the hip support portion A31 in the horizontal direction is less than the maximum horizontal width W2 between the two first edges A311 of the hip support portion A31. In this way, when the infant sits, his / her buttocks can be placed in the widest support area. Especially when the baby is facing the user, the baby's thighs can be supported in a narrower area near the waist belt, so that the thighs can form an ergonomic M-shaped leg.

[0210] It is worth noting that the maximum width dimension between the two first edges A311 of the hip support portion A31 described herein refers to the dimension of the fabric forming the hip support portion A31 located between the two first edges A311 in the connected state.

[0211] Further, as shown in FIG27, the hip support portion A31 has at least one linear closure portion A313, which extends substantially along the longitudinal direction of the child support member A3. Specifically, the linear closure portion A313 is formed by folding and sewing the hip support portion A31 along its transverse width. In this embodiment, the hip support portion A31 has two spaced-apart linear closure portions A313, and both linear closure portions A313 are located near the waistband A1 of the hip support portion A31. The arrangement of the linear closure portions A313 also helps the hip support portion A31 form a pocket-shaped structure with a concave center.

[0212] Further, at at least one location, as shown in Figures 27 to 29, the lateral width distance between the two second connecting portions A518 of the two leg supports A51 is less than the natural lateral width between the two first connecting portions A312 of the hip support A31. The natural lateral width between the two first connecting portions A312 of the hip support A31, as described herein, refers to the actual length of the fabric forming the hip support A31 in its unconnected state, located between the two first edges A311. Thus, in the lateral direction, the hip support A31 is in a wrinkled state at at least one location. Thus, the hip support A31 can be switched between a wrinkled state and an unfolded state in the lateral direction of the child support A3.

[0213] Specifically, as shown in Figure 28, when the infant carrier is not in use, the hip support A31 is in a contracted state in the horizontal width direction of the child support A3. As shown in Figure 29, when the infant carrier is in use, that is, when the infant is riding in the infant carrier, the hip support A31 is in an extended state in the horizontal width direction of the child support A3, and the degree of extension of the hip support A31 can self-adjust according to the different body shapes of the infant. Specifically, when larger infants ride in the infant carrier, their greater weight presses down on the seat area A101, causing the hip support A31 to be stretched downwards and extended. The seat area A101 has a larger depth dimension. Simultaneously, due to the stretching and deformation of the hip support A31, the infant's weight generates a significant force F on the connection between the sides of the hip support A31 and the corresponding two leg supports A51. This causes the hip support A31 to be stretched to a greater extent in the lateral width direction of the child support A3, resulting in a greater degree of extension. The two leg supports A51 expand in directions away from each other. Combined with the compression and concavity of the hip support A31 to form support, the seat area A101 increases in size, making it suitable for larger infants. The infant's legs can form an ergonomic M-shaped leg shape. When smaller infants ride in a baby carrier, due to their lower weight and smaller hip size, the hip support A31 is not stretched excessively downwards. Therefore, the hip support A31 is stretched less in the lateral direction of the child support A3, resulting in a smaller degree of expansion. The seat area A101 is also smaller in the longitudinal direction. Simultaneously, the force F exerted by the infant's weight on the sides of the hip support A31 and the connection points between the corresponding leg supports A51 is smaller. This further reduces the lateral expansion of the hip support A31 relative to the child support A3, causing the two leg supports A51 to be closer together, thus shrinking the seat area A101. This makes it suitable for smaller infants, allowing their legs to form an ergonomically designed M-shaped leg shape.

[0214] Of course, in other embodiments, the first connecting part A312 and the second connecting part A518 may not be directly connected. As shown in FIG36, the hip support part A31 and the leg support part A51 are elastically connected. Specifically, an elastic element A52 may be connected between the hip support part A31 and the leg support part A51, and the elastic element A52 can switch between an extended state and a non-extended state. In this embodiment, the elastic element A52 is a one-piece elastic part. In other embodiments, the elastic element A52 may also be at least one strip-shaped elastic band. The elastic element A52 is connected to the first connecting part A312 and the second connecting part A518 on both sides or both ends of the child support part A3 in the horizontal width direction, respectively, so as to provide sufficient elastic support for the seat area A101.

[0215] Thus, when the infant carrier is not in use, the elastic element A52 is in a non-extended state. When the infant carrier is in use, that is, when the infant is sitting in the infant carrier, the elastic element A52 is in an extended state, and the degree of extension of the elastic element A52 can self-adjust according to the different body sizes of the infant. When the infant carrier carries a larger infant, the elastic element A52 will be extended to a greater extent under the action of the larger weight and larger hip size of the infant, thereby increasing the lateral width of the seat area A101, thus accommodating the larger infant and allowing the infant's legs to form an ergonomic "M" shape. When the infant carrier carries a smaller infant, due to the smaller weight and smaller hip size of the infant, the elastic element A52 will be extended to a lesser extent under the action of the smaller weight and smaller hip size of the infant, thus accommodating the smaller infant and allowing the infant's legs to form an ergonomic "M" shape.

[0216] In another aspect, this disclosure also provides an infant carrier, which, like the infant carrier in the above embodiments, has a leg support A51, a waist belt A1, a shoulder strap A2, and a child support A3 connected to the waist belt A1 and the shoulder strap A2 respectively. The portion of the child support A3 near the waist belt A1 also forms a hip support A31. Two leg supports A51 are disposed on both sides of the hip support A31 in the lateral width direction. One end of the leg support A51 and one end of the hip support A31 are connected to the waist belt A1 and form a first fixed end A511 of the leg support A51 and the hip support A31, and the other end of the leg support A51 is connected to the other end of the hip support A31 and forms a second fixed end A512 of the leg support A51 and the hip support A31. The hip support portion A31 has a first edge A311 on both sides in the lateral direction. The distance W1 between the first fixed ends A511 of the two leg support members A51 located on both sides of the hip support portion A31 in the lateral direction is less than the maximum lateral width W2 between the two first edges A311. This ensures that the hip support portion A31 forms a concave, scoop-like shape when the infant is seated. Specifically, when the infant is seated in the infant carrier, the infant's own weight presses down on the seat area A101, causing the two leg support members A51 located on both sides of the hip support portion A31 to move away from each other. Simultaneously, the hip support portion A31 is compressed and concave to form support, increasing the seat area A101, allowing the infant to form an ergonomically designed M-shaped leg shape.

[0217] A third aspect of this disclosure also provides an infant carrier, which, like the infant carrier in the above embodiments, has a leg support A51, a waist belt A1, a shoulder strap A2, and a child support A3 connected to the waist belt A1 and the shoulder strap A2 respectively. One end of the leg support A51 and one end of the hip support A31 are connected to the waist belt A1, forming a first fixed end A511 of the leg support A51 and the hip support A31. The other end of the leg support A51 is connected to the other end of the hip support A31, forming a second fixed end A512 of the leg support A51 and the hip support A31. In at least one position, the lateral width distance between the two second connecting portions A518 of the two leg supports A51 is less than the natural lateral width between the two first connecting portions A312 of the hip support A31. Thus, the hip support A31 can be switched between a folded state and an unfolded state in the lateral width direction of the child support A3.

[0218] Specifically, when the infant carrier is not in use, the hip support A31 is in a contracted state in the horizontal width direction of the child support A3. When the infant carrier is in use, that is, when the infant is sitting in the infant carrier, the hip support A31 is in an extended state in the horizontal width direction of the child support A3, and the degree of extension of the hip support A31 can self-adjust according to the different body shapes of the infant. Specifically, when larger infants ride in the infant carrier, their greater weight presses down on the seat area A101, causing the hip support A31 to be stretched downwards and extended. The seat area A101 has a larger depth dimension. Simultaneously, due to the stretching and deformation of the hip support A31, the infant's weight generates a larger force F on the sides of the hip support A31 and the connection between the two corresponding leg supports A51. This causes the hip support A31 to be stretched to a greater extent in the lateral width direction of the child support A3, resulting in a greater degree of extension. The two leg supports A51 expand in the direction away from each other. Combined with the compression and concavity of the hip support A31 to form support, the seat area A101 is enlarged, thus making it suitable for larger infants to ride in. The infant's legs can form an ergonomic M-shaped leg. When smaller infants ride in a baby carrier, due to their lower weight and smaller hip size, the hip support A31 is not stretched excessively downwards. Therefore, the hip support A31 is stretched less in the lateral direction of the child support A3, resulting in a smaller degree of expansion. The seat area A101 is also smaller in the longitudinal direction. Simultaneously, the force F exerted by the infant's weight on the sides of the hip support A31 and the connection points between the corresponding leg supports A51 is smaller. This further reduces the lateral expansion of the hip support A31 relative to the child support A3, causing the two leg supports A51 to be closer together, thus shrinking the seat area A101. This makes it suitable for smaller infants, allowing their legs to form an ergonomically designed M-shaped leg shape.

[0219] The above-mentioned infant carriers have at least the following technical effects:

[0220] In the above-mentioned infant carrier, the waist belt A1 and shoulder strap A2 are respectively connected to both sides of the child support member A3 in the longitudinal direction. The part of the child support member A3 near the waist belt A1 forms the hip support part A31. The leg support member A51 is provided on one side of the hip support part A31 in the lateral direction, and the two ends of the leg support member A51 are respectively connected to one end of the hip support part A31 as the first fixed end A511 and the second fixed end A512. The natural longitudinal dimension of the leg support member A51 between the first fixed end A511 and the second fixed end A512 is smaller than the natural longitudinal dimension of the hip support part A31 between the first fixed end A511 and the second fixed end A512, so that the hip support part A31 can be switched between an unfolded state and a folded state in the longitudinal direction of the child support member A3. Thus, when the baby carrier carries a larger infant, the hip support A31 is stretched downwards and extended due to the infant's weight, making the seat area A101 larger in the depth direction to accommodate the larger infant's size. When the baby carrier carries a smaller infant, the hip support A31 is contracted due to the smaller infant's weight, making the seat area A101 smaller in the depth direction to accommodate the smaller infant's size. In this way, the baby carrier can self-adjust the size of its seat area A101 according to the infant's size, and its simple structure makes it easy to use.

In order to simplify the description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
